Multiple buffer overflows in the xfig import code (xfig-import.c) in Dia 0.87 and later before 0.95-pre6 allow user-assisted attackers to have an unknown impact via a crafted xfig file, possibly involving an invalid (1) color index, (2) number of points, or (3) depth.
The Python SVG import plugin (diasvg_import.py) for DIA 0.94 and earlier allows user-assisted attackers to execute arbitrary commands via a crafted SVG file.
